In your tree dependencies I see this :

 +- org.slf4j:slf4j-simple:jar:1.6.4:compile

and this :

   +- org.slf4j:slf4j-api:jar:1.6.1:compile

I suggest you to remove mars-client-interface or kafka, and see what it does...

Thanks! I still need both dependencies, is it possible to exclude transitive dependency and keep my main jars in the project? I've added ` <exclusions> <exclusion> <groupId>org.slf4j</groupId> <artifactId>slf4j-simple</artifactId> </exclusion> </exclusions>` but when I run mvn dependency:tree jar stays there.
Only thing I can do is to give you that link, sorry : stackoverflow.com/questions/547805/…
